Attorney-General Christian Porter said the amendments would be modelled on existing offences which require platforms to notify police if their service is being used to access child pornography.

The laws will also give the e-Safety Commissioner the power to issue notices that bring this type of material to the attention of the social media companies.

As soon as they receive that type of notice, the companies will be deemed to be aware of the material and the clock starts ticking for the hosting platform to remove the material or face penalties.

The laws will still ensure that news media can report appropriately on events which are in the public interest, without showing the violent material itself.

Morrison and Porter were left unimpressed after a meeting with social media companies earlier this week, called in response to the live-streaming of the killing of 50 people in two New Zealand mosques.
